Cluster Sampling

Abstract

Let us consider a situation where a study is to be carried out regarding the indebtedness of farmers of a particular region. For this purpose, a sample of farmers is to be selected. In case, the list of all the farmers (frame) in the region is not available, a simple random sample or a systematic sample of farmers, can not be selected. Even if the frame of all farmers in the region was available, a simple random sample of farmers will result in the sampled units (farmers) being scattered all over the region. This will require a good amount of travel to reach all the selected farmers for collecting information about the indebtedness and will, therefore, involve a formidable amount of travel expenditure.
